Description

Technical Field

[0001] The utility model relates to the field of assembled building components, in particular to an assembled building multi-rib floor slab poly-core mold. Background Art

[0002] With the development of building industrialization, prefabricated buildings have attracted attention due to their advantages such as fast construction speed, easy quality control, and low impact on the environment. In prefabricated buildings, the floor structure is an important component, which directly affects the bearing capacity and performance of the entire building.

[0003] Traditional floor structures are mostly cast on site, which has problems such as long construction period, large material waste, and difficult to ensure construction quality. In order to solve these problems, the prefabricated multi-rib floor structure came into being. It uses prefabricated components, is produced in a factory, and is assembled on site before casting, which greatly improves construction efficiency.

[0004] Although the poly-core mold system of prefabricated building multi-rib floor has many advantages, there are still some technical problems to be solved in practical applications. For example, the utility model patent with announcement number CN214696392U discloses a compression-resistant prefabricated poly-core mold. The poly-core mold used in the construction of prefabricated building multi-rib floor is similar to the poly-core mold structure disclosed in the patent. Its overall square structure lacks an anchoring structure on the surface. During the assembly construction of the floor, the poly-core mold cannot form an effective anchoring with the surrounding frame beams and secondary rib steel bars, and cannot form an anchoring with the finally poured floor concrete. Ultimately, the poly-core mold cannot form a unified whole with the floor, and it is easy to cause local looseness inside the floor, and good seismic resistance and stability cannot be guaranteed. Utility Model Content

[0005] The main purpose of the utility model is to provide a prefabricated building multi-rib floor poly-core mold, which can effectively solve the problems mentioned in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A prefabricated building ribbed floor poly-core mold comprises a bottom plate, a top plate and a foam block, wherein the foam block is fixedly bonded between the bottom plate and the top plate by an inorganic cementitious material, skeleton steel bars are pre-embedded vertically and horizontally inside the bottom plate and the top plate and the skeleton steel bars extend outwardly from all sides, the bottom of the bottom plate is preset with beveled edges all around, and anchoring convex strips and anchoring grooves are respectively arranged on the sides, and a plurality of anchoring spiral grooves are also provided on the bottom surface of the bottom plate.

[0008] Preferably, a layer of fiber cloth for increasing the adhesion of the inorganic gelling material is laid between the bottom plate and the top plate and the foam block respectively.

[0009] Preferably, the beveled edge is a 45° chamfered structure.

[0010] Preferably, the anchoring ridges and the anchoring grooves are integrally cast by a casting mold and a base plate, and the anchoring ridges and the anchoring grooves surround the four sides of the base plate respectively, and the anchoring ridges and the anchoring grooves are parallel to each other and are respectively arranged above and below the skeleton reinforcement.

[0011] Preferably, the anchoring spiral groove is integrally cast by a casting mold and a base plate, the anchoring spiral grooves are arranged parallel to each other, and the inner wall of the anchoring spiral groove has a threaded structure.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, steel bars are embedded in the interior of the base plate and extended out to facilitate insertion into the frame beams and secondary rib steel bars of the floor slab for binding and fixing during assembly, so that the poly-core mold can be well fixed and positioned to improve stability. At the same time, anchoring convex strips and anchoring grooves are arranged around the base plate, and anchoring spiral grooves are opened on the bottom surface of the base plate to increase the anchorage of the poly-core mold and the floor slab concrete poured thereafter, further increasing the connection stability between the poly-core mold and the floor slab, thereby ensuring the stable quality of the floor slab.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] In the description of the present utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. The terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; for ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0022] like Figure 1-3 As shown, a prefabricated building ribbed floor poly-core mold comprises a bottom plate 1, a top plate 9 and a foam block 2. The foam block 2 is fixed and bonded between the bottom plate 1 and the top plate 9 by an inorganic cementitious material, and a layer of fiber cloth 3 for increasing the adhesion of the inorganic cementitious material is laid at the bonding position. By first laying the fiber cloth 3 between the two and then applying the inorganic cementitious material (such as a cement-based material), the bottom plate 1, the foam block 2 and the top plate 9 can be formed into a whole after the inorganic cementitious material solidifies. The addition of the fiber cloth 3 can improve the workability of the cementitious material, making the material easier to apply and shape, thereby significantly improving the material's crack resistance. The addition of fibers can form a uniform stress distribution inside the material and reduce the generation of cracks; at the same time, it can improve the toughness of the connection, and even when it is impacted or bent, it can maintain the integrity of the structure; and it can serve as an anchoring layer to help the foam block 2 better adhere to the bottom plate 1.

[0023] Skeleton steel bars 4 are pre-buried vertically and horizontally inside the bottom plate 1 and the top plate 9, and the skeleton steel bars 4 extend outward from all sides of the bottom plate 1. The skeleton steel bars 4 are all threaded steel bars, which are not only convenient for binding and fixing with the frame beams and secondary rib steel bars of the floor slab, but also can form an anchor with the concrete poured in the frame beams.

[0024] A plurality of anchoring spiral grooves 8 are also provided on the bottom surface of the base plate 1. The anchoring spiral grooves 8 are integrally cast by a casting mold and the base plate 1. The anchoring spiral grooves 8 are arranged parallel to each other, and the inner walls of the anchoring spiral grooves 8 are in a threaded structure with a complex curved surface structure. In this way, after the floor concrete is cast, the anchoring effect between the floor concrete and the anchoring spiral grooves 8 is greater, further strengthening the anchoring effect between the base plate 1 and the floor concrete. Example

[0025] like Figure 3As shown, bevels 5 are preset around the bottom of the base plate 1. The bevels 5 are 45° right-angle chamfered structures, and the surface is in a flat shape, which is mainly realized by the casting mold structure. On the one hand, it is convenient to demould the base plate 1. On the other hand, because the poly-core mold is inverted when assembling, that is, the base plate 1 is located at the top, so when the floor slab concrete is finally poured, the inclined bevels 5 can make the concrete flow to the bottom better, avoiding accumulation on the base plate 1 and increasing the workload of workers to clean up.

[0026] Anchoring convex strips 6 and anchoring grooves 7 are respectively arranged on the sides of the base plate 1. The anchoring convex strips 6 and the anchoring grooves 7 are integrally cast by a casting mold and the base plate 1. The anchoring convex strips 6 and the anchoring grooves 7 respectively surround the sides of the base plate 1, and the anchoring convex strips 6 and the anchoring grooves 7 are parallel to each other. The anchoring convex strips 6 are arranged above the skeleton steel bars 4, and the anchoring grooves 7 are arranged below the skeleton steel bars 4. It is suitable for pouring concrete with large particle sizes. Large stone particles are easy to sink and can be filled into the anchoring grooves 7. The design of one convex and one concave is also to increase the anchoring effect between the base plate 1 and the floor concrete. Example

[0027] like Figure 4 As shown, bevels 5 are preset around the bottom of the base plate 1. The bevels 5 are 45° rounded chamfered structures, and the surface is a smooth curved shape, which is mainly realized by the casting mold structure. On the one hand, it is convenient to demould the base plate 1. On the other hand, because the poly-core mold is inverted when assembling, that is, the base plate 1 is located at the top, so when the floor slab concrete is finally poured, the curved bevels 5 can make the concrete flow to the bottom better, avoiding accumulation on the base plate 1 and increasing the workload of workers to clean up.

[0028] Anchoring convex strips 6 and anchoring grooves 7 are respectively arranged on the sides of the base plate 1. The anchoring convex strips 6 and the anchoring grooves 7 are integrally cast by a casting mold and the base plate 1. The anchoring convex strips 6 and the anchoring grooves 7 respectively surround the sides of the base plate 1, and the anchoring convex strips 6 and the anchoring grooves 7 are parallel to each other. The anchoring convex strips 6 are arranged above the skeleton steel bars 4, and the anchoring grooves 7 are arranged below the skeleton steel bars 4. It is suitable for pouring concrete with large particle sizes. Large stone particles are easy to sink and can be filled into the anchoring grooves 7. The design of one convex and one concave is also to increase the anchoring effect between the base plate 1 and the floor concrete. Example

[0029] like Figure 5As shown, bevels 5 are preset around the bottom of the base plate 1. The bevels 5 are 45° right-angle chamfered structures, and the surface is in a flat shape, which is mainly realized by the casting mold structure. On the one hand, it is convenient to demould the base plate 1. On the other hand, because the poly-core mold is inverted when assembling, that is, the base plate 1 is located at the top, so when the floor slab concrete is finally poured, the inclined bevels 5 can make the concrete flow to the bottom better, avoiding accumulation on the base plate 1 and increasing the workload of workers to clean up.

[0030] Anchoring convex strips 6 and anchoring grooves 7 are respectively arranged on the sides of the base plate 1. The anchoring convex strips 6 and the anchoring grooves 7 are integrally cast by a casting mold and the base plate 1. The anchoring convex strips 6 and the anchoring grooves 7 respectively surround the sides of the base plate 1, and the anchoring convex strips 6 and the anchoring grooves 7 are parallel to each other. The anchoring convex strips 6 are arranged below the skeleton steel bars 4, and the anchoring grooves 7 are arranged above the skeleton steel bars 4. This is suitable for pouring concrete with small particle sizes. Small stone particles are not convenient to sink, so as to avoid the anchoring grooves 7 being located below and not being completely filled. The design of one convex and one concave is also to increase the anchoring effect between the base plate 1 and the floor concrete.

[0031] In actual production applications, when using a mold to produce a poly-core mold, first select a mold of corresponding specifications, then place the skeleton steel bars 4 in advance, then pour cement mortar into the mold, and after the cement mortar hardens, you can get the bottom plate 1 and the top plate 9, then lay a layer of fiber cloth 3 on their surfaces and apply inorganic gelling material, finally align the foam block 2 to cover the top surface of the bottom plate 1, and then cover the top plate 9 on the top of the foam block 2, press it with a heavy object, and after the inorganic gelling material is completely solidified, disassemble the mold to make the poly-core mold movable. In addition, according to actual needs, only the bottom plate 1 and the foam block 2 can be made and bonded together to form a lightweight poly-core mold.

[0032] During assembly construction, the poly-core mold is placed between the frame beams on the floor in sequence, with the foam block 2 or the top plate 9 facing downward and the bottom plate 1 facing upward. After the position is determined, the skeleton steel bar 4 is tied with the frame beam and the secondary rib steel bar next to it. After confirming that there is no omission, the floor concrete is ready to be poured. The poured concrete fills the frame beam and the anchor groove 7 and the anchor spiral groove 8 on the bottom plate 1 in sequence, and they are staggered to form an anchor, which ensures the integrity of the poly-core mold and the floor, thereby improving the construction quality of the floor.
